Electronic dog repellent, dog chaser schematic
Dec 18th
Electronic DOG Chaser Repeller The electronic dog repeller circuit produces a discomforting but not harmful, high frequency sound, audible to dogs but not to humans. Help stop the approach of unwanted dogs at up to 15 feet. It uses 555 circuit at is easy to build, this is a dog chaser schematic that you can do it yourself (more…)
Ultrasonic Sensor Circuit
Nov 4th
This Ultrasonic Sensor Circuit consists of a set of ultrasonic receiver and transmitter which operate at the same frequency. When something moves in the area covered the circuit’s fine balance is disturbed and the alarm is triggered. The ultrasonic circuit is very sensitive and can be adjusted to reset itself automatically or to stay triggered till it is reset manually after an alarm. (more…)
Electronic Siren with Multitone
Sep 24th
This multitone electronic siren is useful for burglar alarms, reverse horns, etc. It produces five different audio tones and is much more earcatching than a single-tone siren. The circuit is built around popular CMOS oscillator-cum-divider IC 4060 and small audio amplifier LM386. IC 4060 is used as the multitone generator. A 100μH inductor is used at the input of IC 4060. So it oscillates within the range of about 5MHz RF. (more…)
Ultrasonic pest repeller
Apr 25th
There are many ultrasonic pest repellers available on the market but a major drawback is that their power output is low and their effectiveness suffers. The electronic pest repeller generates powerful ultrasonic signals to repel pests. (more…)
Dog repellent
Jan 28th
The electronic dog repellent circuit diagram below is a high output ultrasonic transmitter which is primarily intended to act as a dog and cat repeller, which can be used individuals to act as a deterrent against some animals. It should NOT be relied upon as a defence against aggressive dogs but it may help distract them or encourage them to go away and do not consider this as an electronic pest repeller. (more…)
Electronic pest repeller mice repellant
Apr 17th
Electronic pest rat repellents emit high frequency sound waves to create an acoustically hostile environment that effectively repels rodents from protected areas. Sound is inaudible to people and non-rodent pets. It is ideal for environments were the use of poisons is inadvisable or prohibited. Beware mice, rat and mouse :) . It is known that a mice can hear ultrasonic sounds between 30 KHz and 50 Khz and this is pretty loud for his ears and this electronic rodent repellant does just that. (more…)
